Abstract
A high solids spin finish composition is provided which includes a nonionic hydrocarbon surfactant and which has a <FLB> value of less than 11 and a <HLB> value within the range of about 2 to 13.
Claims68
A method for drawing fiber, comprising the steps of:
- providing a fiber;
- applying to the fiber a spin finish composition comprising (i) a nonionic hydrocarbon surfactant having a <HLB> value within the range of 2 to about 13, (ii) a repellent fluorochemical, and (iii) a fluorochemical compatibilizer, thereby forming a treated fiber;
- and
- drawing the treated fiber;
- wherein the solids content of the spin finish has a coefficient of friction of less than about 0.35 and a melting point within the range of about 25° C. to about 140° C.

A method for drawing fiber, comprising the steps of:
- providing a fiber;
- applying to the fiber a spin finish composition comprising (i) a nonionic hydrocarbon surfactant having a 21 HLB> value within the range of 2 to about 13, (ii) a repellent fluorochemical, and (iii) a fluorochemical compatibilizer, thereby forming a treated fiber;
- and
- drawing the treated fiber;
- wherein the spin finish composition is applied at a weight percent of less than about 4% solids on fiber and has a solids content of at least about 70% by weight, based on the total weight of the spin finish composition.

A method for weaving fiber, comprising the steps of:
- providing a hydrocarbon surfactant;
- providing a fluorochemical emulsion;
- mixing the hydrocarbon surfactant and the fluorochemical emulsion such that the resulting composition has at least about 70% solids by weight, based on the total weight of the composition;
- applying the composition to a fiber, thereby forming a treated fiber;
- and
- weaving the treated fiber into an article;
- wherein the composition has a <FLB> value of less than 11 and a <HLB> value within the range of about 2 to 13.
